Haiti Mapping

Published in Data, GeoCommons, OpenStreetMap  |  1 Comment


Haiti Earthquake Relief Maps.jpgThe last 2 days have been filled with coordinating various efforts in gathering information and volunteers responding to the massive Haiti earthquakes of January 12. The analysis team at FortiusOne has put together a news dashboard highlighting the event and current response efforts.

There have been several tremendous groups that have actively been contributing data and tools both with remote developers and responders on the ground. CrisisMappers, CrisisCommons, Ushahidi, OpenStreetMap, just to name a few.

Many data providers have been making their data freely available. This is most notable when looking at Mikel’s screenshots of OpenStreetMap before the quake and after volunteers began tracing over historic maps and newer satellite imagery from Digital Globe and GeoEye.

Other efforts:

  • Ushahidi Haiti is crowd-sourcing reports. You can send a text message to 447624802524, send an email to haiti@ushahidi.com, or send a tweet with the hashtag/s #haiti or #haitiquake.
  • The CrisisCommons Wiki has a list of available data and organizations
  • Sahana has a form to list offices and organizations that are working on the ground
  • GeoCommons search for Haiti has all the datasets and maps that people have contributed for download as Spreadsheet, Shapefile, KML, and more
  • OpenStreetMap’s Project Haiti has a list of datasets and people tracing data

excited about in 2010

Published in Geo, Mobile, OpenStreetMap  |  4 Comments


As always, each new year brings a refreshed feeling of excitement. Perhaps its the long holidays and copious amounts of food, family and fun, or seeing a magic new number on the calendar that makes it feel like “The Future!”, or just a desire to take advantage of an allowed re-emergence of self and goal setting. Of course, time isn’t discontinous, so 2010 isn’t disconnected from the current continuum of development and trends – but it’s still worthwhile to take the time to step back and consider where we are and where we’re going.

Mashable and James, amongst many others, have excellent predictions that will and won’t happen in 2010. Generally they are good insight into trends in the geo and mobile space, although I will take up counterpoint to some of his suppositions on File Formats, Interfaces, OpenStreetMap and Augmented Reality.

File Formats and Interfaces

Geo is definitely becoming mainstream – everyone in my family has a PND, uses Google Maps, and are asking about various location sharing applications. In the next year we’ll see geo become part of the assumed infrastructure, like the timestamp on a post or article, the location will be embedded.

I don’t think TAG (Twitter, Apple Google), as James puts it, will be the only location sharing services. They, along with even more used Facebook, will definitely be the general public interface to location query and sharing – but just because of this reason alone they will have to be very generic, leaving room for specialized location based services to still thrive in niches. FourSquare offers ‘gaming’ or Flickr visual media, and others for music, drinking, sight-seeing, and house finding. They will leverage TAG, or at least TG.

Apple is like the Nintendo of consumer technology – more interested in providing an integrated, compelling experience, and privacy, before full open-ness and engaging with the developer or geek. They’ll still have API’s, but not something like OpenSocial, GeoRSS, or FireEagle integration.

The iPhone, and to lesser extent Android, have been revolutionizing mobile devices. They are truly providing windows into the rest of the web of data combined with the real world. It’s natural for geopatial tools to move into these interfaces, but like any good user experience it won’t be the same capabilities you find on a desktop or browser application. The utilities will be specialized for the small screens, finger inputs, and out-and-about tasks.

For file formats, the Shapefile, unfortunately, isn’t near EOL. Too many tools only speak shapefile, and there is numerous legacy data that is still only available in Shapefile. Sites like GeoCommons offer alternate formats for all the data, but that still won’t remove this basic format. Only when there is a truly open, license free, API to File GeoDatabases (FGDB), and every off the shelf tool can talk that API or Spatialite, will Shapefiles begin disappearing out.

GeoRSS and/or KML, on the other hand, will be in every service that does anything Geo. Looking at any iPhone App review that includes KML (or doesn’t) brings up this point. Near enough everyone has Google Earth on their desktop, and Google is making big pushes in the utilization of Google Earth Plugin for in-browser virtual globes.

Visualization Technologies

To date, we’ve been stuck with either Flash or JavaScript DOM magic (and yes, Silverlight is out there too) in order to do data and geospatial visualization in the browser. As I mentioned, Google has been pushing Google Earth Browser, but also more generally they released O3D, a modern incarnation of X3D, providing for more general capabilities for creating 3D browser experiences. VRML lives!

More recently, there has been a resurgence in vector graphics that don’t rely on proprietary technologies or additional plugins. SVG and Canvas support is pretty widely supported except in the infamous Internet Explorer (which I hear is still being used even today). Examples such as ProtoVis, Cartagen and Tom Carden’s experiments definitely demonstrate that SVG is just on the cusp of being able to do a majority of compelling visualizations capabilities.

Another driver for alternative visualization platforms is the drive to mobile device integration. I don’t see Apple allowing Adobe onto the iPhone anytime soon, and even Android doesn’t have support. What types of visualization make sense is still a very open question – but whatever they are will be done with something like SVG.

Geo Data Skirmishes

James suggests that OpenStreetMap “won’t dominate”. While it won’t dominate, I disagree that it won’t continue to be extremely successful.

Google has recently moved to gathering their own data. They still have a long way to go, with many, many errors in roads, areas, addresses, and businesses and they’re using the crowd to help clean it up. Google is in fact proving the crowd-sourced model. It will be successful. Google is doing it with Google’s data, so there is no positive external benefit to that work – so to the industry it just looks like another data provider. However, with this proven model OpenStreetMap will succeed since any effort built into OSM has a positive benefit to anyone else.

However, there is a major difference in the trajectory OpenStreetMap is taking in the United States compared with Europe and other regions. In most other countries, the governments had very draconian licensing and as such OpenStreetMap was creating data from blank areas – starting from scratch, and building a community of volunteers along the way.

By contrast, in the US a vast majority of the data is free, and becoming more available everyday under the new administration. Therefore the US has a broad coverage of decent data without having first built the user community. So the difficulty here is both in building out community, as well as engaging companies that can do the same thing on their own while retaining proprietary rights to the data.

What’s fascinating, and what signals the ultimate long term success of OpenStreetMap, is that US state, local, and federal government agencies themselves are engaging with OpenStreetMap. They are investigating how to put their data directly into OSM, and possibly even re-incorporate updates and modifications back to their own infrastructures. Some are even considering using OSM toolset as their infrastructure. OpenStreetMap is going through some growing pains with respect to licensing, maintenance, and community – but all necessary steps in moving from a small cadre of hackers to a global, public project.

As we see an increase in open government, specifically driven by the US Administration’s directives, as well as other initiatives such as INSPIRE, this embrace and utilization of open platforms, and repositories, for sharing, federation, and syncronization of data will increase.

And as for augmented reality, it won’t be as big as you think… yet.


OpenSearch descriptions for Flickr, GMaps, BBC

Published in OpenSearch  |  3 Comments


OpenSearch for FlickrSome of the sites I use most don’t support the very nice feature of OpenSearch discovery links. Among these are Flickr and Google Maps – so I first have to navigate to Flickr, then search rather than doing it straight from the browser quick search area.

Fortunately, someone has provided this for me. Just go to http://mvinetwork.co.uk/opensearch/ and click open your OpenSearch discovery and add whatever engines you want!

Hopefully more services that already can support OpenSearch templating add the necessary and simple descriptions and discovery links.

For extra credit, you could extend the OpenSearch definition for GMaps to support location name: http://maps.google.com/maps?q={searchTerms}&hnear={geo:locationString?} – and even Flickr supports (and was the model for) OpenSearch-Geo box search.


Who owns Arunachal Pradesh?

Published in Geo, Society  |  3 Comments


I received an email the other day from a reader of my blog with a very interesting question:

I was looking at a certain area in North East part of India ( State called “Arunachal Pradesh”) which is integral part of India.

Both URL’s have different take. [Google Maps] shows it as Disputed Territory ( with Dash lines) and [Google Ditu] shows it altogether as part of China!

So, that got me unruffled and to question validity of both these sources. How does Ditu differ from Google maps? Whats association between the two and does Ditu has autonomy to change the boundary of the maps as per its wish.

Arunachal Pradesh is a border region between China and India – with 70% of the land being claimed by the Chinese as South Tibet. The border in question was decided in 1914 and called the McMahon Line, but never agreed upon by the Chinese. The Google Ditu vs. Google Map views.

Google Maps vs. Google Ditu

Comparing Google Maps (background) with Google Ditu (foreground tinted red)

Territorial disputes are definitely not a new thing – however what is perhaps alarming is that there are two different representations of reality from the same vendor and data providers. So this is entirely a representational decision that is most likely driven by business and government pressures.

What’s particularly interesting here is that primarily these definitions of boundaries derive from the data providers. You can look in the bottom right corner for who the data providers are. For both versions the providers are the same: TerraMetrics, Mapabc, and Europa Technologies.

So it seems that the cartographic designers at Google Ditu have decided to represent it a certain way. Unfortunately, the map has no additional metadata. As broad consumption of maps increases, there is a commensurate interest in the why and what behind them. Who said these are the boundaries, when were they set, and why are they shown in this language?

And I don’t mean the long reams of unreadable metadata that are the current standards in the geospatial community, I mean human understandable descriptions of the various aspects of the data, while allowing additional discovery to deeper data.

One place that you can look at the data behind the source of the map is in OpenStreetMap. Arunachal Pradesh is shown similar to Google Maps version, and a user could optionally download the data to see the attributes, edit history and sources. Alternatively I can look in GeoCommons for the GADM Admin boundaries of India and see pertinent data on who provided the data, sources, and so on.

Boundary disputes in a bi-directional medium

The representation of boundaries is obviously a very contentious issue in mapping. Maps are perceived, and often do inform, territory. There is a long history of map representation being used to influence, coerce, and force land rights.

Unfortunately, even in a “Web2.0″ world of bi-directional sharing and collaboration, with maps we’re still often forced to accept a particular viewpoint. They have on-the-ground meaning and political impact. A well known example of this were the first “edit wars” in OpenStreetMap with the names of places in Cyprus. The resolution was to by default abide by the on the ground signage, but also store both versions and allow users to provide their own personalized perspective.

Understanding, awareness, and discussion about these issues is the reason for projects like OpenStreetMap or GeoCommons where you can download the information, build and share your own maps that represent your perspective.There

There isn’t an easy answer here – with companies such as Google there are obviously market, and government, forces that direct how to represent contentious issues. The best solution is to offer background, open data, and alternative perspectives. Without a voice, citizens are relegated to discussions by officials they may, or may not, have elected – and no meaningful way to illustrate their interpretation.


Geography Week and GIS Day at UVA

Published in Geo, Presentation


UVA Academical Village MapThis week is National Geography Awareness Week. Hopefully you’re celebrating it your own way by enjoying a map, thanking a cartographer, or even doing some mapping yourself! It’s clear that mapping and geo have entered the mainstream – everyone is engaging with maps through navigation systems, friend location finders, and virtual globes. The next step is to make people aware of the potential for them to personally engage with place and location for personal interests, business uses, and community building.

This Wednesday, I will be giving the GISDay plenary talk at the University of Virginia in Charlottesville. My talk, “Neogeography: from Tower to Town Hall” will discuss how the movement to broad, public engagement and collaboration, particularly around geographic contexts through web maps, mobile devices, and open data can build stronger communities, improved research, representative government and better livelihoods of people. (link to the UVA Calendar)

Around Washington, DC you can join the OpenStreetMapping party in Bethesda, MD on Saturday, or you can check out the large list other activities at GISVirginia. Whatever you do, spread the word and encourage people to go out and map something.
